When pressed by 2 4 1, the pressure of the brake fluid in the internal flow path 4 〇 of the front wheel side hydraulic pressure control device 1 rises compared to the state where the brake lever 2 4 1 is not grasped by the rider. That is, when the rider grasps the brake lever 2 4 1 and the piston 5 1 of the master cylinder 5 ○ of the front wheel side hydraulic pressure control device 1 is pressed by the brake lever 2 4 1, the front wheel side hydraulic pressure control device 1 The detected pressure of the pressure sensor 5 9 is higher than when the brake lever 2 4 1 is not grasped by the rider.

Based on the detection result of the pressure sensor 5 9, the control signal of the brake lamp 2 2 1 of the bicycle 2 〇〇 is output. Therefore, when the brake system 100 equipped with the front wheel side hydraulic pressure control device 1 and the rear wheel side hydraulic pressure control device 2 is mounted on the bicycle 200, it is detected whether or not the brake is applied. Therefore, a dedicated brake switch is not required. Therefore, when the brake system 100 equipped with the front wheel side hydraulic pressure control device 1 and the rear wheel side hydraulic pressure control device 2 is mounted on the bicycle 2000, the signal line connected to the brake switch is also unnecessary. Therefore, in the front wheel side hydraulic pressure control device 1 and the rear wheel side hydraulic pressure control device 2 according to the present embodiment, when the brake system 100 is mounted on the bicycle 2 0 0, the area around the handlebar 2 3 3 is It is possible to suppress the complexity more than before.

The control signal of the brake lamp 2 2 1 when the brake fluid of the wheel cylinder 2 5 3 is depressurized by the anti-lock brake control is the control signal of the brake lamp 2 2 1 when the anti-lock brake control is not performed. It is an identifiable signal. As a result, the bicycle 200 can make the brake lamp 2 2 1 shine differently depending on whether or not the anti-lock brake control is performed during braking, for example. For example, during braking, the bicycle 2 〇〇 turns on the brake lamp 2 2 1 when the anti-lock brake control is not performed, and turns off the brake lamp 2 2 1 when the anti-lock brake control is performed. In this way, by making the break lamp 2 2 1 shine differently depending on whether or not the anti-lock brake control is performed during the braking of the bicycle 2 〇〇, for example, the rear of the bicycle 2 〇〇 The running vehicle can know that the braking force of the bicycle has changed. Therefore, when the pressure of the brake fluid in the internal flow path 40 drops due to the change in the open / closed state of the control valve 5 5, the control signal of the brake lamp 2 2 1 is output to improve the safety of the bicycle 200. improves. The control signal of the brake lamp 2 2 1 output from the control device 70 of the front wheel side hydraulic pressure control device 1 and the rear wheel side hydraulic pressure control device 2 is for control other than lighting the brake lamp 2 2 1.

That is, when the rider begins to grasp the brake lever 2 4 1, the pressure of the brake fluid in the internal flow path 40 begins to rise immediately. For this reason, the brake system configured in this way 1 〇〇 In, the delay between the time when the rider starts braking the bicycle 2 2 1 and the time when the brake lamp 2 2 1 lights up can be suppressed, and the safety of the bicycle 2 0 is improved.

As mentioned above, when braking force is generated on the wheels of the bicycle, the conventional method of turning on the brake lamp based on the detection result of the brake switch is to brake because the rider does not hold the brake lever 2 4 1. Lamp 2 2 1 cannot be illuminated. However, when the pressure detected by the pressure sensor 5 9 increases during the operation of the pump 60, the rider does not hold the brake lever 2 4 1 by outputting the control signal of the brake lamp 2 2 1. When braking force is generated on the wheels of the bicycle 2 〇〇, the brake lamp 2 2 1 can be lit. As a result, the vehicle traveling behind the bicycle 200 can tell that the braking force of the bicycle has changed. Therefore, when the pressure detected by the pressure sensor 59 increases during the operation of the pump 60, the safety of the bicycle 200 is improved by outputting the control signal of the brake lamp 2 2 1.
